凸轮从动轴承 凸轮轴承 滚子从动轴承 bearing
IKO滚子从动轴承在厚壁外圈中装入针状滚子，是设计用于外圈旋转的轴承。为了能直接与对方滑轨面接触使用，滚子从动轴承的外圈外径备有球面和圆柱面，球面外圈的轴承可缓和因安装误差带来的不均等的负荷，而圆柱外圈的轴承与对方滑轨面的接触面积大，适合于大负载负荷或低硬度的滑轨面。滚子从动轴承有附带保持架的和满滚子的，附带保持架的适合于转适高的部位，满滚子的适合于转速低，摆动运动，承载重负荷的部位。滚子从动轴承除开放型之外，还有屏蔽型和密封型，屏蔽型轴承的侧板与外圈之间的间隙小，形成迷宫。密封型轴承在屏蔽型的迷宫部装入密封垫片，可防止异物侵入。滚子从动轴承有丰富的型号，可为各种工作条件选择相应的轴承，广泛用于凸轮机构和搬运装置的直线运动部分。滚子从动轴承分为三种：分离型滚子从动轴承、非分离型滚子从动轴承和双列圆柱滚子从动轴承。
